Disney has stated that the plates on the table weren't a planned "hidden mickey" and last time we were there (Aug `12) they were not arranged in the shape of a mickey anymore.

Quoted from an official "There is a drawing on the table by the Imagineers for exact placement of each place, glass, etc. There is no Mickey in this plan. The cast members have made this Mickey on their own, thus it will disappear when the table is reset by the "official" drawing."

In the graveyard scene there is an official hidden mickey on the grim reaper figure.
